I have a brand new pair of Algonquins that are wired to run off the 'B' speaker channel of my Denon AVR-2308CI. This works fine, but I want to be able to adjust the volume independently of the main speakers on the 'A' channel. My first thought is a basic 2 channel amp. A real plus would be an amp with an RF remote so I could adjust the volume from out in the yard.
Does anyone know if there is such a thing? What would you recommend for a decent, cheap 100W amp?

How about one of these Dayton Amps from Parts Express. They seem to be highly rated and inexpensive, although it looks like a remotes out of the picture.

That looks like a cheap solution, although a little more power would be nice.
